Towards Strong Field Tests of Beyond Horndeski Gravity Theories
Jeremy Sakstein, Eugeny Babichev, Kazuya Koyama +2
Theories of gravity in the beyond Horndeski class encompass a wide range of scalar-tensor theories that will be tested on cosmological scales over the coming decade. In this work,…
Disformal Theories of Gravity: From the Solar System to Cosmology
Jeremy Sakstein
This paper is concerned with theories of gravity that contain a scalar coupled both conformally and disformally to matter through the metric. By systematically deriving the non-rel…
Testing Gravity Theories Using Stars
Jeremy Sakstein, Bhuvnesh Jain, Vinu Vikram
Modified theories of gravity have received a renewed interest due to their ability to account for the cosmic acceleration. In order to satisfy the solar system tests of gravity, th…
Towards Viable Cosmological Models of Disformal Theories of Gravity
Jeremy Sakstein
The late-time cosmological dynamics of disformal gravity are investigated using dynamical systems methods. It is shown that in the general case there are no stable attractors that…
